The Chilean ore/oil motor vessel Valparaiso
was on a voyage from Ras Shukeir.
on the Gulf of Suez coast of Egypt to Quintero Chile
loaded with 118,000 tons of crude oil
when she ran aground on rocks during very bad weather
about 180 miles south of Talcahuano
about lat 38.21S, long 74.00W on May 17, 1986.
She managed to refloat herself later on the same day,
using her own power
but ripped open one of her tanks in the process,
spilling some 2,000 tons of crude into the sea.
The Valparaiso then continued to Talcahuano,
where her cargo was offloaded.
Due to the severity of the damage
sustained by the grounding,
the vessel valued at $6.4m was declared
a constructive total loss
and sold to Taiwanese shipbreakers for demolition.
